Fish population model R code

We developed an age-structured population matrix model to perform population viability analysis for Lower Missouri River (LMR) shovelnose sturgeon (Scaphirhynchus platorynchus). We investigated potential effects of the commercial fishing moratorium put in place to help protect the similar-appearing pallid sturgeon (S. albus). The model applies different components of total variance in life history parameters at different levels: sampling variance (parameter uncertainty) between model iterations; temporal variance (temporal environmental fluctuations) between time steps within iterations; and individual variance (individual differences) within each time-step. The model predicted annual rates of population increase...

Crayfish morphometric measurements, burrow attributes and occupancy in response to physical burrow barriers

Data were collected in association with the application of two physical barrier treatments, bentonite clay (a sealing agent) and expanding foam (an insulation sealant), in natural pond-burrows to suppress or kill the invasive red swamp crayfish (Procambarus clarkii). Data include burrow diameter and depth, crayfish sex and size, and determination of the treatment reaching the burrow chamber.

Acoustic Telemetry Evaluation of Invasive Red Swamp Crayfish (Procambarus clarkii) Behavior in Southern Michigan (Summer 2021)

This study deployed acoustic telemetry into a red swamp crayfish-infested water retention pond (1.0 ac) near Novi, Michigan to document the movements and behavior of telemetered red swamp crayfish (Procambarus clarkii). Telemetry was setup in the pond for approximately 3 months. Spreadsheets include telemetry data with position estimates for individual crayfish.

Electro-olfactory responses of Grass Carp, Bighead Carp, and Silver Carp to the amino acids L-alanine, L-arginine, L-aspartic acid, L-asparagine, L-glutamine, and L‑glutamic acid

Using juvenile individuals of 3 species of carp (Family: Cyprinidae), we tested the potential for six amino acids to elicit an extracellular electro-olfactory response within the naris using gelatin-based electrodes. The amino acids L-alanine, L-arginine, L-aspartic acid, L-asparagine, L-glutamine, and L‑glutamic acid were tested on Grass Carp (Ctenopharyngodon idella), Bighead Carp (Hypophthalmichthys nobilis), and Silver Carp (H. molitrix) to provide a comparison among amino acids both within and among species. Each row in the data set represents exposure to a single amino acid. Each individual fish was exposed to up to four amino acids sequentially in a random order, representing a trial; each individual was...
